Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed by the human body when exposed to a radio frequency (RF) electromagnetic field; although, it can also refer to absorption of other forms of energy by tissue, including ultrasound.It is defined as the power absorbed per mass of tissue and has units of watts per kilogram (W/kg).

SAR is usually averaged either over the whole body, or over a small sample volume (typically 1 g or 10 g of tissue). The value cited is then the maximum level measured in the body part studied over the stated volume or mass.

When we buy a mobile phone, we focus on its look, features, etc. But do not ever try to know what effect it will have on our health? How dangerous is the radiation from him? In this regard, you think the Government of India and mobile companies do not think seriously. Therefore, they design phones with radiation less than SAR Limit.

In India mobile devices (mobile, smartphones, fables, tabs etc.) are designed according to the limits of Radio Frequency Energy (Exposure Limit) set by the Government of India. In any mobile device, the radio frequency energy should not exceed the fixed limit.

SAR.

The measure of measuring exposure limits is called a specific absorption rate (special absorption rate) or summary (SAR).

Fixed SAR Limit for mobile devices in India is 1.6 watts / kilogram.

So if your phone's abstract limit is more than the limit, change your phone immediately and buy the phone with at least the limit limit while buying a new phone. Because phones with more abstract limit have very bad effects on your brain and body cells.
